  "summary": "Reviewed this Go test-data generator, which deterministically builds legacy AEAD test vectors from local crypto primitives and prints them to stdout. I checked for install hooks, network or exfiltration behavior, credential or environment harvesting, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in the target file.\nReviewed `aws-lc/crypto/x509/x_x509.c`, which implements X.509 ASN.1 object construction, parsing, serialization, and signature accessors. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise patterns in this file.\nThis file is an ARM64 Montgomery square routine for P-384 field arithmetic. I reviewed it for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",
